3 Terms and definitions

  GB/T18930 and the following terms and definitions apply to this document

3.1

  Coating resistant refractory castable

  It is a refractory castable made of aluminum silicate material, silicon carbide and other main raw materials and additives.

4 Brand

  According to the SiC content, the refractory castables are divided into five grades: KIP-25, KIP-35, KJP-45, KIP-55 and KIP-65. Among them, K, J and P are the initial letters of “resist”, “knot” and “skin” in Chinese pinyin, and the numbers following are the mass percentage content of SiC content.

5 Technical Requirements

  The physical and chemical indexes of refractory castables against crust should conform to the provisions of Table 1.

6 Test methods

6.1 Sample preparation was carried out according to GBT 4513.5.

6.2 Silicon carbide is measured according to GB/T 16555.

6.3 Flexural strength at room temperature, compressive strength at room temperature, flexural strength at high temperature, permanent line change of heating and maximum operating temperature shall be measured according to GB/T4513.6. The high temperature flexural strength refers to the high temperature flexural strength of the sample after pre-burning at 1100℃C for 3h.

6.4 Alkaline resistance was measured according to GB/T 14983.

6.5 The resistance to crust was determined in accordance with Appendix A.

7 Quality assessment procedures

7.1 Batch

  Products according to the same brand batch, each batch does not exceed 60t. Raw materials or production process changes should be set up separately.

7.2 Rules for sampling and conformity determination

7.2.1 Sampling of products shall be carried out in accordance with GB/T 4513.2.

7.2.2 Chemical composition, compressive strength at room temperature, permanent line change under heating, and resistance to crust are the acceptance inspection items. The average value of the test results conforms to the provisions of Table 1, which is qualified. If there are unqualified items in the test results, double the number of samples shall be taken in accordance with 7.2.1 to recheck the unqualified items, and the average value of the retest results shall meet the requirements of Table 1, then the batch of products shall be judged qualified; Otherwise, it is disqualified.

7.3 Form of conformity assessment

  Conformity assessment can be carried out in the form of supplier declaration, user certification or third-party certification.

8 Packing, marking, transportation, storage and quality certificate

8.1 Packing, marking, transportation and storage shall be carried out in GB/T 15545.

8.2 The product shall be issued with a quality certificate and instruction manual. The quality certificate shall indicate the name of the supplier, the name of the demander, the date of production, the contract number, the number of this document, the name of the product, the brand number, the batch number, the physical and chemical index and the shelf life.
